Code has been discovered in Jelly Bean that hints strongly at a future version of the OS introducing Profile switching capabilities. This would enable a device to carry different settings, apps, and customizations for different users, similar to modern OS's like OS X and Windows. An XDA post by zanderman112 details how this can be done, even in its current unfinished code state.

Hello Android fans!

Did you see the Raspberry Pi people are putting the last touches to an
Android port. Yep, (Ice Cream Sandwich on the Raspberry Pi. With Plex
already out for the Android, and XBMC being developed - could this be
the cheapest media steamer ever? :)

Google sent out an email to developers detailing a number of changes to the policies around Google Play. Some notable changes affect spam and ads, as well as payments:

" ⁃ We’ve added clearer details to the payment policy, and guidelines on how we will handle cancellations in our new subscription billing feature
⁃ We are restricting the use of names or icons confusingly similar to existing system apps in order to reduce user confusion
⁃ We are providing more detail on the kinds of dangerous products that are not allowed on Google Play. For example, apps that disclose personal information without authorization are not allowed.
⁃ We are giving more examples of practices that violate the spam policy."
Also, any apps distributed via Play MUST use Google's payment system, including for in-app purchases

Hey AAA crew,Just got an Sprint Galaxy S3 and I notice when I
use the Google Music app, somehow it is seeing the podcast I have
downloaded using pocket casts. How can I make it stop! When I am
listening to my music on shuffle, all of a sudden a podcast will play.
I love pocket casts for my pod-casts, but when i want music, i only
want music. Do you know of a way to stop Google music from searching my
phone for MP3 files? BTW this never happened with my 2.3 HTC EVO
Thanks!
